Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a multi-functional folding cleaning cart. Background Technology

[0002] Cleaning carts refer to multi-functional cleaning carts or handcarts used for cleaning and sanitation or for transporting materials. They are widely used in cleaning operations and material transport in public places such as hotels, shopping malls, commercial buildings, real estate developments, hospitals, schools, offices, libraries, exhibition centers, clubs, and other venues.

[0003] Most existing cleaning equipment is bulky and has a fixed structure, requiring a lot of space for storage, which is especially inconvenient for users living in small apartments or condominiums. Due to limited indoor space, many families struggle to find suitable storage locations, resulting in cleaning tools being placed haphazardly, affecting the tidiness of the room and the safety of passage.

[0004] Therefore, a multi-functional folding cleaning vehicle needs to be designed to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of cleaning equipment, such as large size, fixed structure, space-consuming storage, and inconvenience for small apartments, this utility model provides a multi-functional folding cleaning cart.

[0006] The technical implementation scheme of this utility model is as follows: A multi-functional folding cleaning cart includes a liquid storage box, a slider, an extension box, electric casters, a dual-axis motor, a lead screw, a connecting seat, a control module, an observation board, an injection pipe, a support plate, a telescopic rod, a brush plate, a return spring, and a spraying assembly. A slider is fixedly connected to the bottom of the liquid storage box. Extension boxes are symmetrically connected and communicate with each other in the middle of the slider. Electric casters are symmetrically fixedly connected to one side of the bottom of each of the two extension boxes. A dual-axis motor is fixedly connected to the top of the liquid storage box. Lead screws are fixedly connected to both ends of the output shaft of the dual-axis motor. Connecting seats are fixedly connected to one side of the top of each of the two extension boxes. The middle section is connected to a lead screw via a thread. A control module is fixedly connected to the top of the liquid storage frame. The control module is electrically connected to the electric universal wheel and the dual-axis motor. An observation plate is fixedly connected to the rear of the liquid storage frame. An injection pipe is connected and communicated with the top of the liquid storage frame. Support plates are fixedly connected to the bottom of the slider and the bottom of the two expansion frames. Each support plate is at the same horizontal height. Telescopic rods are symmetrically fixedly connected to both sides of the bottom of each support plate. A brush plate is fixedly connected between each telescopic rod. Multiple return springs are connected between each brush plate and the corresponding support plate. Multiple return springs are wound around each telescopic rod. A spraying assembly is provided at the front of the liquid storage frame.

[0007] Optionally, the observation panel can be made of transparent material.

[0008] Optionally, the liquid spraying assembly includes a liquid pump, a connecting pipe, and a nozzle. The liquid pump is connected to and communicates with the front of the liquid storage frame. The liquid pump is electrically connected to the control module. The connecting pipe is connected to and communicates with the front of the liquid pump, and the nozzle is connected to and communicates with the top of the connecting pipe.

[0009] Optionally, the front of the nozzle has a ring array with multiple small holes.

[0010] Optionally, it also includes a T-connector, a connecting pipe, and a nozzle, wherein the bottom of the connecting pipe is connected to and communicates with the T-connector, the bottom of the T-connector is connected to and communicates with the connecting pipe, and the bottom of the connecting pipe is connected to and communicates with the nozzle.

[0011] Optionally, it also includes a servo motor, a notched gear, a spur gear, and a torsion spring. The servo motor is fixedly connected to the front of the liquid storage box.

A torsion spring is connected between the upper part of the connecting pipe and the lower part of the nozzle.

[0012] This utility model has the following advantages: 1. This utility model uses a dual-axis motor to drive a lead screw transmission to realize the lateral movement of the expansion frame on the slider. Combined with the synchronous expansion and contraction of the electric universal wheels, it achieves flexible adjustment of the overall width of the cleaning cart. When not in use, the equipment can be folded and retracted to save storage space. This solves the problem of large size, fixed structure, and space occupation of cleaning equipment. At the same time, the brush plate automatically conforms to the ground under the action of the return spring, adapting to different terrains and improving cleaning efficiency and stability.

[0013] 2. This utility model starts the liquid pump through the control module, pressurizes the cleaning liquid in the storage box, and then delivers it to the nozzle for uniform spraying through the connecting pipe, so as to achieve efficient wetting and cleaning of the ground. After spraying, the residual liquid can automatically flow back to the storage box, avoiding pipe blockage and waste of cleaning liquid caused by liquid residue. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Example 1: A multi-functional folding cleaning cart, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the system includes a liquid storage frame 1, a slider 101, an extension frame 2, electric casters 3, a dual-axis motor 9, a lead screw 10, a connecting seat 11, a control module 19, an observation plate 7, an injection pipe 8, a support plate 12, a telescopic rod 13, a brush plate 14, a return spring 15, and a spraying assembly. A slider 101 is welded to the bottom of the liquid storage frame 1. The middle of the slider 101 is symmetrically connected to and connected to the extension frames 2. Electric casters 3 are symmetrically screwed onto the bottom sides of the two extension frames 2, which are far apart from each other. A dual-axis motor 9 is screwed onto the top center of the liquid storage frame 1. Lead screws 10 are welded to both ends of the output shaft of the dual-axis motor 9. Connecting seats 11 are screwed onto the top sides of the two extension frames 2, which are close to each other. Lead screws 10 are threadedly connected to the middle of the two connecting seats 11. A control module 19 is screwed onto the front top of the liquid storage frame 1. Block 19, control module 19 is electrically connected to electric universal wheel 3 and dual-axis motor 9. An observation plate 7 is glued to the middle of the rear of the liquid storage frame 1. The observation plate 7 is made of transparent material, which makes it easy to observe the remaining amount and usage status of the liquid inside the liquid storage frame 1, so as to replenish it in time. The top rear side of the liquid storage frame 1 is connected to and connected to the injection pipe 8. The bottom middle of the slider 101 and the bottom front side of the two expansion frames 2 are all welded with support plates 12, and each support plate 12 is at the same horizontal height. The bottom sides of each support plate 12 are symmetrically welded with telescopic rods 13. Each telescopic rod 13 is screwed with a brush plate 14. Each brush plate 14 is connected to the corresponding support plate 12 with multiple return springs 15, and the multiple return springs 15 are wrapped around each telescopic rod 13. The front of the liquid storage frame 1 is provided with a liquid spraying assembly.

[0023] When this equipment is needed, the dual-axis motor 9 is first started via the control module 19. The output shaft of the dual-axis motor 9 rotates forward or backward, driving the two lead screws 10 to rotate forward or backward, which in turn drives the connecting seat 11 and the extension frame 2 to move laterally outward or inward on the slider 101. At the same time, the electric universal wheels 3 move outward or inward, thus expanding or contracting the overall width of the cleaning cart. Cleaning fluid is injected into the storage box 1 and the extension frame 2 through the injection pipe 8. The liquid level is checked by observing the observation plate 7. The electric universal wheels 3 are then started via the control module 19. The electric universal wheels 3 rotate forward or backward, allowing the entire equipment to move in different directions. At the same time, the return spring 15 provides downward pressure, keeping the brush plate 14 in contact with the ground. When the ground is uneven, the telescopic rod 13 retracts, and the return spring 15 absorbs the impact force and is compressed. The support plate 12 bears and supports the brush plate 14, ensuring stable cleaning of the ground. The control module 19 stops the dual-axis motor 9, controls the opening and closing of the extension frame 2, stops the electric universal wheels 3, and controls the direction and speed of the equipment's movement.

[0024] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the spraying assembly includes a pump 4, a connecting pipe 5, and a nozzle 6. The pump 4 is connected to the middle of the front side of the liquid storage frame 1. The pump 4 is electrically connected to the control module. The connecting pipe 5 is connected to the front side of the pump 4. The nozzle 6 is connected to the top of the connecting pipe 5. The nozzle 6 has multiple small holes arranged in a ring array at the front, which can realize uniform atomization spraying of cleaning liquid, expand the coverage area, improve cleaning efficiency, and reduce liquid waste.

[0025] When it is necessary to spray cleaning liquid on the ground, the liquid pump 4 is started by the control module 19. The liquid pump 4 starts to run, draws cleaning liquid from the storage box 1 and pressurizes it. The pressurized cleaning liquid is guided to the nozzle 6 through the connecting pipe 5 and sprayed on the ground. When the control module 19 stops the liquid pump 4, the cleaning liquid remaining in the connecting pipe 5 can flow back to the storage box 1 naturally, or be left in the connecting pipe 5 for the next use.

[0026] like Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, it also includes a three-way connector 16, a connecting pipe 17, a nozzle 18, a servo motor 20, a gear 21, a spur gear 22, and a torsion spring 23. The bottom rear side of the connecting pipe 5 is connected to and connected to the three-way connector 16. The bottom of the three-way connector 16 is connected to and connected to the connecting pipe 17. The bottom of the connecting pipe 17 is connected to and connected to the nozzle 18. The servo motor 20 is screwed on the upper front side of the liquid storage frame 1. The servo motor 20 is electrically connected to the control module 19. The output shaft of the servo motor 20 is welded with the gear 21. The bottom rear side of the nozzle 6 is welded with the spur gear 22. The gear 21 and the spur gear 22 mesh with each other. The upper part of the connecting pipe 5 is connected to the lower part of the nozzle 6 with a torsion spring 23.

[0027] The pressurized cleaning fluid is guided to the three-way connector 16 through the connecting pipe 5. After the cleaning fluid reaches the three-way connector 16, part of it continues to be transported along the direction of the connecting pipe 5, while the other part is diverted to the spray nozzle 18 through the connecting pipe 17. The spray nozzle 18 sprays the cleaning fluid onto the cleaned ground. When the control module 19 stops the pump 4, the cleaning fluid remaining in the connecting pipe 17 can flow back to the storage box 1 by gravity, or be retained in the connecting pipe 17 for the next use.

[0028] When the nozzle 6 needs to oscillate to spray liquid, the servo motor 20 is started by the control module 19. The output shaft of the servo motor 20 rotates clockwise, driving the toothed gear 21 to rotate. The toothed gear 21 meshes with the spur gear 22, causing the spur gear 22 to drive the nozzle 6 to rotate clockwise. The torsion spring 23 is deformed by the force, and the cleaning liquid is continuously sprayed out through the nozzle 6, forming a fan-shaped or linear spray coverage. When the toothed gear 21 rotates to the toothless area, the spur gear 22 loses power input, the nozzle 6 stops rotating, the torsion spring 23 resets, and the nozzle 6 automatically returns to the starting position under the action of the torsion spring 23. The servo motor 20 is stopped by the control module 19, and the nozzle 6 will stop oscillating.
